The AirTAC GFR600C25AF2 AirTAC Filter Regulator 1 in PT1 Auto Drain is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR600C25AF2 is a size 600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This configuration carries a 1 in PT1 port, a 40 um standard filtration element, an automatic drain that expels collected condensate without manual attention, and an embedded square gauge reading in psi so the set pressure is always visible. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), the maximum inlet pressure is 1.0 MPa (145 psi), the operating temperature range is -5 to 70 C (non-freezing), and the size 600 bowl is aluminium alloy. A mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options that include a 5 um element (code W), manual or differential-pressure drain, alternative gauge scales (MPa / psi / bar), an external round gauge, G (BSPP) or NPT threads, and a no-bracket variant. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing figures for your application on request.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Installed at a main compressed-air drop in a manufacturing plant, this filter regulator cleans the supply of water and pipe scale and holds a steady pressure to the air tools and cylinders served by that drop.
On a bottling or packaging conveyor, pneumatic cylinders for pushing, clamping and diverting containers need clean, regulated air; this unit provides both functions in one body at the line's supply point.
Pneumatic clamps and swing cylinders on a CNC machining fixture perform repeatably when supply pressure is stable; this filter regulator conditions the air and lets the setter read and hold the clamping pressure in psi.
Size 600 with a 1 in PT1 port is the largest step in the GFR range, so it is the natural choice when the line diameter and air demand at the point of use are at the top of the family's span; smaller sizes 200-400 step down through 1/8 in to 3/4 in ports. Drain type is a real decision: this unit has an automatic drain, which suits installations that are not checked daily; manual drain suits attended stations, and the differential-pressure drain is the catalogue default. The 40 um element fitted here is the standard grade; specify code W for 5 um where finer particulate removal matters. The square gauge on this unit reads psi; MPa and bar scales are available, and an external round gauge can be ordered instead. PT thread is the standard; G (BSPP) and NPT are order options, and a no-bracket variant exists.
Because flow is published only as curves and not as a single rated number, we do not quote a flow figure here. Send us your application details and we will confirm sizing against the datasheet curves before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves, not as a single rated figure, so we do not quote a flow number here. Tell us your line size and air demand and we will confirm the sizing against the datasheet curves on request before you order.
This configuration is coded A for an automatic drain, which expels collected condensate from the bowl without anyone opening it - useful for drops that are not visited daily. The catalogue also offers manual drain and a differential-pressure drain (the default); for GFR units with automatic or differential-pressure drain the regulator adjustment range is 0.15-0.9 MPa (20-130 psi), while manual-drain versions start lower at 0.05 MPa. Ask us to quote the drain variant you need.
